Is the Heat Shrinkable Tube resistant to high temperature? What is the working temperature?

Heat Shrinkable Tube is resistant to high temperatures. Secondly, the continuous working temperature of the Heat Shrinkable Tube varies from 125°C to a maximum of 260°C, mainly depending on the material and model of the Heat Shrinkable Tube. Different materials and models of Heat Shrinkable Tube have different working temperatures, and the corresponding Heat Shrinkable Tube model needs to be selected according to the working temperature environment of the product.

Heat Shrinkable Tube are mainly divided into 6 categories according to different materials: PE ordinary Heat Shrinkable Tube, adhesive Heat Shrinkable Tube, military-standard Heat Shrinkable Tube, PVDF Heat Shrinkable Tube, fluororubber oil-resistant Heat Shrinkable Tube, and Teflon Heat Shrinkable Tube. , the following will take everyone to understand the working temperature and high temperature resistance of various types of Heat Shrinkable Tube, and the high temperature resistance is from low to high:
1. PE ordinary Heat Shrinkable Tube is the most widely used model, mainly used for binding and insulation of wire harnesses in the electronic field, and the maximum continuous working temperature can reach 125°C.
2. Adhesive Heat Shrinkable Tube include double-walled Heat Shrinkable Tube, medium-walled Heat Shrinkable Tube and thick-walled Heat Shrinkable Tube. The difference between the two is that the wall thickness is different. Their working temperatures are basically the same, and the rated working temperature is also 125°C.
3. Since the military standard Heat Shrinkable Tube meets the military standard requirements of high flame retardancy, its working temperature is slightly higher than that of ordinary Heat Shrinkable Tube, up to 135°C.
4. PVDF Heat Shrinkable Tube is divided into soft type and semi-hard type. PVDF heat-shrinkable tubing can be made of medical grade. When ordering, you need to explain to the manufacturer of the heat-shrinkable tubing in advance. The maximum working temperature of soft PVDF heat-shrinkable tubing can reach 150°C, and the maximum working temperature of semi-rigid PVDF can reach 175°C.
5. The fluorine rubber oil-resistant Heat Shrinkable Tube is not only resistant to high temperature, but also insoluble in high-temperature oil. It has excellent physical and chemical properties, and the maximum temperature can reach 200°C.
6. Teflon heat-shrinkable tubing has the highest high-temperature resistance in the heat-shrinkable tubing industry, and its Teflon material has become the king of plastics. Therefore, the Heat Shrinkable Tube produced by PTFE is also a leader in the industry, which can withstand some acid and alkali solutions, and its maximum continuous working temperature can be stabilized at 260°C.
Heat Shrinkable Tube can withstand high temperatures. You can choose the corresponding model according to your needs. It has strong compatibility and selectivity. Heat Shrinkable Tube not only have excellent high-temperature resistance, but also have good low-temperature resistance. The most conventional ordinary Heat Shrinkable Tube are resistant to The low temperature is minus 45°C without cracking, and the Teflon Heat Shrinkable Tube is resistant to minus 65°C without cracking.
